UNITED STATES PATENT OFFICE. FISHER H. LIPPINOOTT, OE PHILADELPHIA, PENNSYLVANIA, ASSIGNOR'TO AMERICAN SODA FOUNTAIN COMPANY, OE BOSTON, MASSACHUSETTS, A

CORPORATION OF NEW JERSEY.

Re it known that I, FISHEE H. LIPPINcOT'r, a c1tizen -of the United States, residing irrthe ciftg) and county of Philadelphia, in the State o and useful Improvements in Syrup-Dispens- 1n Apparatus, of which the following is a ful, c ear, and exact description, reference bein1T had to the whic A My invention relates to ap .aratus for dispensmg hquids and is particu arly applicable to soda fountains as an adjunct thereof for the dispensing of such liquids as Syrups-Or analogous ingredients for beverages.

In the drawings hereto annexed which illustrate an embodiment of my invention and improvements, Figure 1 is a plan view of the apparatus; Fig. 2 is a' front elevation thereof; 3 is a vertical section on the line -m of Fig. 1 Fig. 4 is a vertical section on the line g/-g/ of Fig. 1 and Fi .'5is a horizontal section on the line z-z o Fig. 2'.

In the accompanying drawings 1 is a jar suitable 'as a reservoir for llavoring Syrups and the like. At the bottom of the jar 1 and, in the form Shown, near one end thereof, there is provided a well or measuring cham- In the form of measuring chamber or well shown in the drawings, the sides thereof are substantially cylindrical except at the upper end where they flare outwardly at 2a) as Seen in Figs. 3 and 4. This well or measaccompanylng drawings, of

uring chamber in the form shown in the draw- 35 ings is made in a separate iece from the jar 1 and detachably secured t ereto, the securement in the instance shown consisting in the provision of the upper end of the well or measuring chamber 2 with a peripheral flange 3 whichv is ada ted to seat upon the lower surface of a circu ar recess 4 in the bottom of the jar, the said recess surrounding an opening in the latter. A portion of the periphery of the measuring chamber or well 2 is screw threaded and' is an annulus or thimble correspondinglyv screw threaded. In the form of apparatus shown, the measuring chamber or Well is inserted through the opening in the bottom ofthe jar (marked 4a in Figs. 3 and 4) from the inside of the jar and the flange 3 thereof brought to rest on the lower ed e or bottom Wall ofthe recess 4. The annu us 5 which has a liange 5EL at the top is screwed Specification of Letters Patent. Application filed August 18.1904.l Serial No. 221,216.

ennsylvanla, have invented certain new SYRUP-DISPENSING APPARATUS.,

onto the measuring chamber or well until the said flange 5 bears against the under sideof the jar 1 thereby holding the 'measuring chamber 2 iirmlyl in position.

The measuring chamber or well aforesaid performs its function b determining the amount of li uid which 1s expelled or dispensed at eac operation of the mechanical devices which cooperate with the measuring chamber as will presently be explained.

` 6 is a plunger rod arranged to slide vertically in a lid or cover 7, the said cover being dome-shaped, in the form shown, and resting upon a part 8 of the top of the casingl which the syrup jar 1 'is supported. The cover 7 closes over the opening Qin the said casing. In order to maintain the cover 7 in place, I secure around the said opening 9 a vertical ring or flange 10 over which the lower part of the cover 7 fits.

Secured to the lower or inner end of the plunger rod and concentrically with the measurin chamber 2, there is a plunger 11 Patented June 25,1907.

whereof t e diameter is such that the plunger has a sliding twith the cylindrical portion of the well or measuring chamber. In the form of my invention. shown in the drawings, the plunger rod is made tubular so that it serves, as will presently be observed, the function of a conduit for the removal of displaced liquids as Well as that of the means for imparting movement to the plunger 11.

The upper end of the plunger rod has, in the `illustration shown in the drawings, a head or enlargement 12 which constitutes external operating means for the plunger as will hereinafter be described. A discharging nozzle 6a is provided for delivering displaced liquid into the tumbler or other receptacle and in the illustration of my invention shown in the drawings, this nozzle 6a constitutes a continuation ofthe tubular plunger rod. v The nozzle 6a by communicatingwith the conduit through which liquid displaced from the measuring chamber is expelled from the apparatus, serves to conduct said liquid to a convenient point for its final discharge and for this purpose the Outer end of the nozzle is downwardly turned and projects preferably beyond the side of the casing as will be seen.

in Figs. 1 and 4.

The plun er rod passes through a hollow cylindrical c amber 13 which is formed in the IOO lid or cover 7. ber 13 has an internal flange 14 upon which 1s seated a spiral compression spring 15; the

upper end of this spring which is contained within the chamber 13 bears against a collar 16 formed u on the plunger rod. This collar 16 acts a so as a stop against the under side of the cover 7 to limit the upward movement of the plunger rod. e

A lug '17 on the iiange 10 in conjunction with the corresponding slot 19 in the side of the cover 7 serves to prevent the latter from turning; the plunger rod 6 is prevented from turning in the cover 7 by suitable means such, for example, as one or more splines 19 on the plunger rod, the said splines entering corresponding guide slots or notches in the cover 7. Thus the nozzle 6a mounted on the tubular plunger rod will be maintained in itS required position projecting over the edge of thc casing.

Having described the construction of the aforesaid embodiment of my improvements (with the exception of certain means for effecting ad'ustment which I will hereafter allude to) proceed to explain the mode of operation thereof. The jar 1 haying been charged with syrup or other liquid. if it be desired to discharge lor dispense a uantity of the li uid, say into a glass laced eneath the nozz e 6, the plunger ro by means of the external operating knob 12, is forced down against the stress of the spring 15 thereby carrying the plunger 11 into the measuring chamber 2 and thus expelling the liquid from the measuring chamber into the conduit, rovided in the present instance by the tubu ar plun er rod 6, and thence out through the nozz e 6a. lf the plunger 11 is made to expel its entire contents from the measuring chamber, the quantity of liquid delivered at the nozzle 6EL will correspond substantially to the excess of capacity of the measuring chamber over that of the conduit itself.

On releasing the plunger rod, the spring 15 will return it to the normal position shown in the drawings, whereu on the measuring chamber will again fill wit syrup, the means for its refilling being shown in the speciiic illustration described as the annular orifice between the Haring mouth 2a of the measuring chamber 2 and the plunger 11. When the llquid has become exhausted from the jar 1 the operator removes the cover 7 from the casing and withdraws therewith the displacement dispensing devices which, if desired, may be examined or cleaned, refills the jar 2 through the opening 9 and then replaces the cover 7 with its dispensing devices attached so that by mere replacement of this cover thev operative mechanism is returned to its normal positlon 1n,readmess to perform lts functions.

Syrup jars are usually made of porcelain The lower end of this chamand therefore vary somewhat in dimensions and if, as in the apparatus shown for illustration of my improvements, a measuring charnber attached to the jar be employed, the distance of the bottom of such measuring chamber from" the. normal position of the plunger 11 may vary, and itis then desirable, 1n order that the pllunger may occupy the proper position wit relation to the measuring cup (i. e. just above the lower part ofthe flare2), to make the plunger vertically ad- 'ustable upon the plunger rod. To this end have shown the lower end of the plunger rod provided with a screw thread (Figs. 3 and 4), and the plunger 11 correspondingly threaded so that in effect the plunger 11 is a nut on the plunger rod. Thus the plunger may be set in any osition of adjustment on ,the plunger rod an secured therein by means of a lock nut 20 (Fig. 3) on the plunger rod above the plunger. Also, in order to adjust the quantity of liquid which may be forced from the measuring chamber or well through the conduit in the lunger rod and delivered from the nozzle 6&3 provide means for varying the reciprocating movement of the plunger rod and therefore of the plunger; in this instance I accomplish adjustment by means of a screw threaded nut 21, screw threading the s lines 19 so that the nut may be adjusted) u or down. This nut 21 sto ping against t e cover 7 limits the extent of ownward movement ofthe plunger rod and plunger.

The casing shown in the drawings, whereof the piece marked 8 is a part of the top, supports the jar 1 in its interior. This casing as shown is suited to the reception of only one jar; but may obviously be enlarged if desired to contain more than one jar.

The interior of the casing should in practice be kept cold by ice or other refrigerating means, in. order to keep the syrups in the jars at the lower temperature desired. The arrangement of parts which is characteristic of my improvements lends itself especially to the economical maintenance of low temperature inthe interior of the jar-containing casing, because the top of the casing as well as its sides and bottom is kept closed and the dispensation of Syrups by means of my improvements does not interfere with this desired closed condition of the casing. The lid orcover 7 carries mounted inor on it the syrup displacing devices so that whenever it is desired to replenish the jar the only opening made through which cold air may escape from the casing` is that which suflices to lift out the displensing devices; and as this opening is on t e upper part of the casing very IOO IIO

little loss of refrigerant can result while the l syrup j ar is being refilled. Again the removal for cleansing of the displacing devices involves very little loss of refrigerant and when the cover 7 is replaced the apparatus is intached directly thereto` so that it is easy to cleanse the jars or to substitute one jar for another, as no rearrangement of moving men chanical parts is necessary for either purpose..

What claim is:
